Duking it out at Hearn

April 13, 2020 - Toronto - Hearn Power Station

Marion Nash Reports:

Desmond saw two Peregrines on the ground locked together in battle. He did not want to see either or both killed so he walked up to them and broke up the fight. not sure who would have been the victor or if the nest sight battle will continue but he will be watching and keeping us posted.

here are the 2 after the fight.

!!! Two residents still very much on site at Hearn!

June 4th - 2016

The second nest site visit of the day, it was down to the Hearn plant on Unwin Ave to check up on the status and activities of the resident Hearn peregrines. It was only seconds after my arrival that I was able to locate the resident adult male roosting way up on one of the smoke stacks blinking white lights,,, - (approx. 3/4 the way up the old smokestack). Minutes later, the adult female appeared from the south and landed on the upper superstructure roof only meters from her mate. For the next three plus hours, I watched them interact with one another, including two different hunting forays.

Sadly, both birds were too far away for me to get any leg band numbers, but it was quite obvious that the two peregrines are very much still calling the Hearn plant their home.

At no point during the 3 plus hours that I was there, did I see either one of the peregrines go into or come out of a nesting location on the plant and neither of them spent any of their time to the north of the superstructure. They both spent most of their time roosting on the same spots that we had observed the pair on in several seasons past.

As such, I don’t believe that the pair have produced any offspring so far this season. :-(

Peter at Home

Harry Crawford Reports:

I made it down to the Hearn Generating Station just before 9am.  Peter was sitting on the ledge just above the sagging traditional nesting spot.  Unfortunately, I didn’t see any indication of Angela, not that she couldn’t have been around somewhere.

!!! Both adults are still very much on territory and active at Hearn, but it might appear that the nest site has failed again this year!

Hi All,

I was on my own checking out Hearn today, so just one pair of eyes unfortunately.

In the first picture, all the red arrows are where I saw Peter, and the blue arrows are the unbanded female (I assume Angela as she was named). I had my scope, so yes, Peter and yes, unbanded female.

I got there at 5:30pm and saw only Peter. When he flew to the roof that looks broken (3rd pic), I saw he had a stash on the ledge just above. He was making a lot of clucking sounds while eating, but I couldn’t see any other bird. Then he flew around to the extreme left arrow and sat there for a long time.

Angela did not appear until 7:30pm. I don’t know where she came from. I heard the calling and looked up. They flew to the (centre photo), each landing on a separate ledge, and lots more clucking and chittering sounds. I saw Peter at this spot the last time we were here, and thought that’s where they might be nesting. They were there for about 15 minutes and then flew to the right, Peter on the corner and Angela on a vertical post. They were there until I left around 8:15pm

I’m not sure what is going on in the building .. I saw lasers and heard lots of music .. and it was quite loud, so hard to hear any peregrine calls over that. The sounds I heard were during the silent interludes.

!!! Two territorial peregrines observed on site,, with lots of copulation going on at Hearn!!

Good news, as Desmond has reported seeing both adult peregrines down at the Hearn plant, and love is in the air for sure!! After being able to spend several hours down at the Hearn plant, Desmond reports seeing both peregrines on site, and involved in several copulation sessions throughout his observation period.
While we have yet to identify “the spot” in which the pair have decided to lay their eggs, it would appear that they are both still very much around and looking again to the Hearn Plant to lay their eggs and raise their family.

We were able to confirm that the resident adult male is still Peter, (produced in Hamilton at the Hamilton Sheraton hotel),, but his mate has not yet been identified as yet this year.

The next mystery is to locate and identify the nest location…………..

Stay tuned………………

!!! Territorial activity observed at Hearn!!

I had an opportunity to get down to the old OPG Hearn plant on Unwin Ave this evening on my way home to check on the status of the resident Hearn peregrines, and was delighted to see at one of resident peregrine falcons on site, overlooking its domain. Actually, the adult colored peregrine was perched high up on the smoke stack, roosting on the top of the west facing white strobe light , 3/4 the way up the smoke stack.

I watched the peregrine roosting on the strobe light for approx.40 minutes after my arrival, and then watched it make an incredible dive and stoop on a large black coloured bird close to the base of the smoke stack. The peregrine dove and stooped down so fast that I couldn’t even follow it with my bare eyes, and it was only after the explosion of feathers when it hit the smaller bird, did I realize that it had come that close to the base of the smoke stack and the ground level!!. Moments later, it re-appeared back in my view against the lighter blue sky with a kill in its clutches and I watched the peregrine utilize the air movements to gain altitude as it snaked back and forth around the west side of the smoke stack finally ascending to the highest upper most white blinking strobe light (almost at the very top of the large smoke stack on the south side), where it finally landed and eventually chowed down to eat its prize!

What an incredible display of determined, focused talent!!

I finally departed at dusk when the light simply disappeared making it too difficult to see much of anything. As a foot note, I have long since forgotten just how dark it gets down there, given the lack of street lights and other ambient light that would normally come from other hi-rise buildings.

Sadly, I didn’t have my camera this go-round, but I promise that I won’t forget it next time!!!
Stay tuned,,,,,,

!!! Peter spotted and photographed out on the spit.

A big thanks to Mike for sending in some of his recent photos of Peter that he snapped of Peter while out on the spit December 27th - 2014.
I was at the Spit on 27 Dec 2014. I went looking for the Purple Sandpiper at the end of Peninsula A but instead I found Peter the adult male Peregrine. His leg is tagged 46Y. Peter was preening the whole time I was there. He’s looking very active and healthy. Here are a few pics.

!!! Renewed nesting activity in question?

June 08, 2014 - Toronto - Hearn Power Station

CPF Postmaster Reports:

June 8th - 2014I visited Hearn today from 10:30 - 11:15 am. Neither bird visible in the area until after 11 when I noticed one perched on a pipe at the side of the building - not sure if it was the male or female. The only other thing of note was a pile of what I assumed were pigeon feathers on the ledge where I had observed the pair on Friday.

Lots of activity at the nearby Raven nest though - looks like the young are beginning to fledge.

!!! Second nesting attempt at OPG Hearn plant!

Yesterday (June 5, 12:30 pm), I was able to observe the pair from Unwin Ave. on a possible nest site to the right of the stack. At first I could only see one bird (maybe the male?) and he seemed to be working on something - at least he seemed to be spending a lot of time with his head down. Then the second bird (who seemed a bit larger so I’m guessing female) appeared from deeper in the structure and walked past the first bird to the ledge. They remained together for several minutes before the male flew away to perch on a pipe on the side of the building (I’ve seen one perched in this same spot several times this spring). I stayed for a total of 20 minutes and neither had moved by the time I had to leave.

Here are a few photos to give you an idea what was going on - sorry for the poor quality!

Angela and Peter Appear to Have a Failed Nest

June 01, 2014 - Toronto - Hearn Power Station

Bruce Massey Reports:

I came down to Hearn Generating Station today and met up with Harry at the site to check in on the resident adults and their progress towards nesting.  When I arrived there was nobody visible.  I walked to the east and checked the back side of the stack and again saw nothing.  I moved back out front to the south side of the building and within 20 minutes both birds arrived from the south.  Peter and Angela landed on the small opening to the west of the old nest area and both disappeared into the grid work.  Angela appeared and flew up to the vent on the south side where she roosted and Peter finally emerged and had a great soar above the structure.  His flights eventually took him off to the north and out of view.

Based on these observations both Harry and I agree that they are not incubating nor brooding any young.  They seem to be interested in the south side ledges once again leading us to the conclusion that the first nest has failed and that a reclutch may follow.

We will keep you updated as we learn more.
